- I don't have explicit examples of where we would want to use FATE. The obvious place is
that we don't want multiple hosts sending the same data more than once, but we also want to
make sure we re-send data that failed to send the first time around.

The ongoing work on replication reminds me that an upgrade can't happen while a FATE operation
is in flight. So, as the design here develops, that's something to keep in mind.
